What to do?

I was talking to this guy and we decided that we wanted to take a break because he has a lot going on right now and then a few days ago he calls me and says he alot going on and he doesnt wanna hurt me...end of convo. He wouldnt let me get anything out. I wanted to write a letter or do something to reach out to him and see if would at least talk to me so we can come to an understanding. What you do you ladies think ? Hes done this before and once I expressed how i felt and that i wasnt gonna give up on him everything was fine. He tends to seclude himself when things are hard to understand or explain.
